Handle Guzzle exception and get HTTP body

Question

I would like to handle errors from Guzzle when the server returns 4xx and 5xx status codes. I make a request like this:

$client = $this->getGuzzleClient();
$request = $client->post($url, $headers, $value);
try {
    $response = $request->send();
    return $response->getBody();
} catch (\Exception $e) {
    // How can I get the response body?
}

$e->getMessage returns code info but not the body of the HTTP response. How can I get the response body?

Answer 1

Guzzle 6.x

Per the docs, the exception types you may need to catch are:

• GuzzleHttp\Exception\ClientException for 400-level errors
• GuzzleHttp\Exception\ServerException for 500-level errors
• GuzzleHttp\Exception\BadResponseException for both (it's their superclass)

Code to handle such errors thus now looks something like this:

$client = new GuzzleHttp\Client;
try {
    $client->get('http://google.com/nosuchpage');    
}
catch (GuzzleHttp\Exception\ClientException $e) {
    $response = $e->getResponse();
    $responseBodyAsString = $response->getBody()->getContents();
}
